Uncertainty, weak hands and small market cap are the main reason for this kind of volatility. In stock market even professionals panic if there is uncertainty. It becomes too volatile at some point. As an example is the recen 1500 point drop in DOW. Once it all stabilizes it will calm down and starts to rise steady. That’s when everyone starts to love bitcoin and other coins that survive. Which could be one the reasons for volatility as well, there are too many cryptos not meant to survive. We just have to stomach it as you said 🤢.
